Abstract
Background: This study analyzed the association between the volume of heart surgeries and treatment outcomes
for hospitals in the last five years. Methods: Hospitals that perform heart surgeries were chosen
throughout Korea as subjects using from the Health Insurance Review and Assessment Service. The treatment
outcome of the heart surgeries was defined as the mortality within 30 postoperative days, while the annual
volume of the surgeries was categorized. Logistic regression was used as the statistical analysis method, and
the impacts of the variables on the heart surgery treatment outcomes were then analyzed. Results: The
chance of death of patients who received surgery in a hospital that performed 50 or more surgeries annually
was noticeably lower than patients receiving operations from hospitals that performed fewer than 50
surgeries annually, indicating that the chance of death decreases as the annual volume of heart surgeries in
the hospital increases. In particular, the mortality rate in hospitals that performed more than 200 surgeries
annually was less than half of that in hospitals that performed 49 or fewer surgeries annually. Conclusion:
These results indicate that accumulation of a certain level of heart surgery experience is critical in improving
or maintaining the quality of heart surgeries. In order to improve the treatment outcomes of small hospitals,
a support policy must be implemented that allows for cooperation with experienced professionals.
